How do you find the degree of ionization of the solutions when
accounting for the dillution effect of adding 10 mL of water? Also
for the second page, how do you calculate pH with a buffer using
the Henderson-Hasselbalch equation?
Solution 2 - 10.0 mL of 0.1 M HC2H302 +10.0 mL H20 Measured pH_2.42 To determine the [H3O+], account for the dilution effect of adding 10.0 mL of water, and use MV1 = M2V2 Degree of lonization of solution 2...

2. how would you find the Ka of solution 4, after it is
diluted from solution 3? the measured pH was 4.98 which gave a [H+]
concentration of 1.05x10^-5.

Make 1.00 L of 1.0 M buffer pH 6.2. How much of each component do you need to use? You have NaHmalonate and 10.0 M NaOH. The pka of malonate is 5.69 and the MW is 126.1 g/mol. I know the answers (NaHmalonate: 126.1 g, NaOH: 76 mL, H2O: 924 mL). I am just wanting to understand the mechanism of how to reach these numbers. The question says to use the Henderson-Hasselbalch equation, nOH- = nA-, and the hint says...
